Put me down for a set in white! I wish rear offset was more like +15 to +22 but I can always run a spacer

 

i dont know you too well but i hate you too =D.

 

that would be sick. no doubt

 

Holy Hell that is wide

quick question I am running 19 9.5F & 10.5R with stock fenders (for now) zeal coilovers, whats the largest tire size I can run without modding my fenders?

 

I'm interested, just a little confused on what to order. My issue is this, I have a set of drag radials that i have been using for the strip that come in 265/40/18 and i dont feel like buying a wider radial when i already have these, but wouldnt an 11.5 rim be strecthing the tire a little too much? I'm running hotchkis springs on the car right now.Also what is the projected weight of this rim going to be?

 

Which ZEALS do you have and are they a true coilover in the rear? Are you asking whats the widest tire you can run on your current setup or on the 11.5?

 

I dont think you will be able to use a 265/40/18 on a 11.5 +29 wheel, if you were to somehow manage to fit that tire on there, it would be stretched like hell. The idea of running a 11.5 rear is to get as much rubber as you can without getting into rubbing issues. Im assuming you are running DR for traction purposes so running a 315/35/18 on the 11.5 rear will get you much more contact patch then your current setup giving you better traction for the horses your putting down.

 

Zeal V6 Funtion Coil Overs and yes true in the rear. widest tire I can run now?

Thanks

 

What offset are your wheels?

 

O GOD I cant remember I would say standered offset for SF challenges bro. Nothing costom

 

Probably a 10.5 +23. Im assuming you are running a 285, if you cut your fenders I bet you can get a 295 on there but Im almost certain you wont be able to find a 295/35, itll probably be a 295/30.

 

running 245 F and 275 rear now but they have that stretched look to them. I cant cut my fenders because my doluck fenders will need a place to attached to.

 

subscribing...

I can't wait to see pics of a true 315 or 325 in the rear of the Z. I'm assuming you will roll the fenders, set your camber to around -2 degrees and slam her to get it workout?

What kind of tires do you have? The brand of tire makes a difference too. I ran SF Challenges, 19x9.5 +28 19x10.5 +23 with a 255/35 front and 275/35 in the rear and my rear was not stretched at all. I ran Toyo T1R and it looked perfect. If you are going to run a wide body, you may think about getting a lower offset in the rear but then you wouldnt be able to get as wide of a tire. You should really consider these 11.5 rears with your wide body, how much more wider is the rear on the Do Luck?

 

Weve already done the measurements and I dont think too much camber adjustment is needed for a 315 but yes, you definitely have the idea, negative camber definitely helps.

 

how come no CE28 option?

bumpity for Andy and brian to make the rest of us inferior..

 

That's the problem with trying to fit too wide of a tire back there, everyone resorts to severe camber and streched tires because of the low offset. Also, you end up with the same traction as a 255 in a straight to semi-straight line if your entire setup isn't perfect. It seems no one ever offers the perfect offset, rim width, camber degree or suspension drop combo. I have seen it more than once, people with (wide tires) and tire wear on only 2/3 of the tire.

To maximize a full tread pattern on a 295/30/19 (during DD), you need a camber degree of -1. I know this for a fact as it was the only way I could get complete even tire wear. My offset is +29 on a 10.5" rim, I'm now dropped roughly 1" in the rear and my wheels stick out beyond the fender with my fender lip completely shaved off for clearance. The clearance between my stock shock absorber and fender edge is 12-5/8 inches. This equates to a 325 series tire fitting (as in wedging the tire) between these two points. If you're under full susp. compression on a 315 and on a "perfect setup", you will have roughly 5m of clearance on each side, it will rub due to wheel wobble. IMO< not safe at all... and very dangerous!

My point, a (11.5"@+29) rim on a normal Z is not going to be safe. The fender would have to be pulled out by a body shop or go wide-body to get it to work. Either that or run a 315/25/19 series tire, basically a rubber band...and an expensive one at that!

I'm not trying to discourage anyone from trying new stuff, it's just I've been down this road of maximization while taking into consideration longevity and safety, all while trying to make it look perfect on a non-widebody Z.

Hell, if I had my choice, I would throw on the same set of tires that the Veyron uses. BTW, I read replacements cost $12k!!!!!!!!!!!! It would look something like this
